To facilitate assembly the lower half of the block, that is, thatportion below the line 22 in Figure 1 may be split in a vertical planeincluding the longitudinal median line of spring I) as indicated inFigure 2 at a.

By the construction described it will be evident that the block ofyielding non-' metallic material is securely held in position with framemember while its lower end is permitted a degree of movement to allow'for spring deflection. Separation of the parts, however, is prevented bythe bolt 9 which secures the cup in place and which passes through anaperture in the end of the spring, the aperture being of sufiicientdiameter to prevent a metal to metal contact and the upper end of thebolt being spaced from all metal parts by arrangement within the recess(1 Various modifications may be made in the arrangement andconfigurationof the component parts going to make up the cushion connection accordingto the present invention and no limitation is intended by the foregoingdescription except as indicated in the accompanying claims.

What I claim is:

1. In a cushion connection of the character described the combinationwith two parts,.one of which parts is to be connected to and supportedby the other part, of non metallic yielding material engaging one of theparts, means to secure said material to the other part, a cup-shapedelement to maintain the part engaging portion of said non-metallicyielding material under compression, and means to maintain saidcupshaped element in compression relation with the non-metallicmaterial.

2. In a cushion connection of the character described the combinationwith two parts, one of which parts is to be connected to and supportedby the other part, of non-metallic yielding material engaging one ofthe. parts,

means to secure said material to the other part, a cup-shaped element,and a bolt to maintain the cup-shaped element in position.

3. In a cushion connection of the character described the combinationwith two parts, one or which partsis to be connected to and supported bythe other part, of non-metallic.

yielding material engaging one or the parts, means to secure saidmaterial to the other part, a cup shaped element and a bolt carried withthe non-metallic material to maintain the cup-shaped element inposition.

4. In a cushion connection of the character described, the combinationwith a vehicle frame member and aleaf springof a cupshaped membercarried with the frame member, a yielding non-metallic block engagingthe end of the spring, means to secure the block within the cup-shapedmember, a cupshaped member enclosing that portion of the block engagingthe end of the spring, and a bolt seated within the yieldingnon-metallic material and retaining the last named cup in position.
